Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish an improved hose-nozzle,which shall be so constructed that the fireman Who holds the nozzle canshut oft' the Water Wholly or partly Whenever desired, and which shallpresent no through a hole in the side of the bulb O, which hole isclosed by a screw-cap, c". The cap c is so formed that its outer surfacemay be continuous With the surface of the bulb O. Upon the inner end ofthe nozzle A is formed a segment, E, of a bevel-gear Wheel, the teeth ofwhich mesh into the teeth of the segment F .of a bevel-gear wheel formedupon the top of the plug D.

By this construction, by turning the nozzle A in one direction, the plugD will be turned to allow the Water to ow through the said nozzle, andby turning the nozzle in the other direction the Water will be shutoft'. The bulb O may be made With double walls, to give it the necessarystrength Without making it too JAMES H. MGGONNELL.
